Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
bronchitis is more.
Bronchitis is common after
lung infection like
pneumonia and can cause breathlessness.
In my opinion, you should definitely
consult pulmonologist and get done clinical examination of respiratory system and PFT (pulmonary function test).
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only.
You may need inhaled treatment.
Yes, you can try herbal medicines, no harm in it.
But first consult pulmonologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
